Strength training

Can anyone recommend a good training routine for building the kind of strength and conditioning that is required for bullseye shooting?

Using the search function I found this thread:

I think in most strength training routines for shooting,  too much attention is paid to the arms, and not enough to core body, and leg strength.  

I have noticed when my legs are stronger, I shoot better in a match and don't tire as easily.  
If you knees can take it, I recommend squats, push-ups, and sit-ups. 
Sustained cardio isn't as helpful as short bursts of squats, or stair climbing in my opinion.   A low pulse rate is helpful, but not as helpful as it is in rifle shooting. 
If you feel strong, everything improves, including your hold.
